MEANS FOR TRANSMITTING POWER FROM CAR-AXLES TO DYNAMOS.

SPEGIFIGA'J LON forming part of Letters Patent No. 504,132, dated August 29, 1893.

Application filed April 29, 1893- Serial No. 472,317. (No model.)

To all whom it mag concern.-

Be it known that we, MORRIS MOSKOWITZ and SAMUEL YOUNG, citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in, Means for Transmitting Power from a Car- Wheel Axle to a Dynamo in the Car; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked Ehereon, which form a part of this specifica- In Letters Patent of the United States, granted to us June 6, 1893, and numbered 498,985, We have illustrated and claimed a novel form of mechanism for transmitting power from a car-wheel axle, when the car is in transit, to a dynamo within the car to generate electricity. In this application, itis our intention to illustrate and claim a novel form of speed regulating device adapted to be used in connection with any suitable form of mechanism operated from the car-wheel axle, said speed regulating device thereby being adapted to operate the dynamo within the car, whereby the dynamo is successfully connected with the car-wheel axle to maintain an equal power and uniform speed of the dynamo, regardless of the speed at which the train may be traveling, and at all times to cause the dynamo to run in the same direction, whether the car is moving forward or backward.

The invention therefore consists-in the novel form of speed regulator, to be hereinafter more fully described and finally embodied in the clauses of the claim, by means of which the rotary movement of the armature shaft of the dynamo is maintained constant; and the invention further consists in the combination of this speed regulator with suitable means for operating the same from a carwheel axle.

The object of the invention therefore resolves itself into the obtaining from the variable speed of the car-Wheel axle, a constant and uniform speed of the dynamo.

The invention is illustrated in the accompanying sheets of drawings, in which Figure 1 is a front elevation of our novel form of speed regulator, and Figs. 2 and 3 are regulator, taken on line 55in Fig. 1. Fig. 6

is a detail view of a governor and its connecting parts, used in connection with the machine illustrated in said Figs. 1, 2 and 3, and Fig. 6is

a vertical section taken on line 6-6, in said Fig. 6. Fig. 7 is an enlarged detail view of a screw-threaded rod having a follower thereon to be provided with a strap adapted to beconnected with the speed regulator. Fig. 8 is 'an enlarged sectional view of a system of clutch gears connected with the shaft of the governor illustrated in said Fig. 6, for causing the rotary motion of said shaft in one direction, irrespective of the forward or backward movements of the car truck and its car-wheel axle, and Fig. 9 is an end View of said clutch gearing. Fig. 10 is an enlarged sectional view of a speed-regulating governor used in connection with the machine illustrated in Fig. 1, geared with one of the shafts of the conepulleys illustrated therein, and by means of a suitable system of gearing causing the reciprocatory movements of the follower and band employed in connection with the screwthreaded rod illustrated in Fig. 7, and Fig. 10 is a horizontal section of one of the friction devices shown in said Fig. 10, looking downward.

Similar letters of reference are employed in each of the above described views to indicate corresponding parts.

In said views, A indicates a railway car and a one of the car-wheel axles, which rotates inthe usual form of boxes or bearings a of the car-wheel truck. By means of any suitable form of gearing and link chains or belts B, which may be of the form illustrated and claimed by us in the Letters-Patent hereinabove mentioned, the rotary motion of said axle a is communicated to a shaft barranged in suitable bearings b secured to the bottom of the car A, in any convenient manner. On said shaft 1) is arranged asuitable pulley or wheel 6 over which passes a belt 12 to a pulley or wheel 0' arranged on a shaft 0, substantially as illustrated in Fig. 4, for driving the intermediately arranged speed mechanism which operates the dynamo and regulates the speed of the latter. The general arrangement and construction of said speed mechanism for finally operating the dynamo, and which mechanism is embodied in a complete machine, are illustrated more especially in Figs. 1, 2, 3 and 5.

To the floor of the car or to any suitable base adapted to besecured to the floor of the car, are secured the frames or supports dand d on the one side of the said speed mechan ism, and on the other side of the said machine are the supports or frames d and (1 said supports being provided at their top with the inwardly extending arms 01 and d and these are held in position and secured to a connecting plate d by means of suitable bolts d Arranged between said supports d and d, and d 'a'nd (this a suitable base 6, which may be provided with the feet e, adapted to be secured to the floor'of the car by belts or screws 6 as will be seen from said Fig. 1. Extending up from said base a at the ends thereof are two standards a and c providedwith bearings e in which rotates a governor shaftf. As will be seen from Figs. 1, 2, 3, 5 and 6, to the one end of said governor shaft is secured a bevel wheel f, and meshing with said bevel wheel are two bevel wheels 0 and 0 which are loosely arranged on sleeves c and 0 respectively secured on said shaft 0 by means of a key 0 as shown in Fig.8. The ends of each of said sleeves c and 0 form ratchetwheels c and c ,the rat'chetteeth thereof being set in opposite directions, sa'id wheels being provided with spring-actuated pav'vlsc and 0 respectively, said pawls being set in opposite ways and adapted toeugage with the teeth of said ratchet Wheels. By this opposite arrangement of the ratchetteethandthe pawls acting in opposite directions, anda'lso, owing to the fact that the bevel Wheels c a'nd c are loosely arranged on said shaft 0, saidg'overnor shaft f will at'all timesma'intain its revolutions in the same direction, whether the'car is moving forward or backward,which will cause the dynamo and the several'partsof'the intermediately arranged mechanism to rotate in one and the same direction. Said'shaft o, as will be seen more especially from Fig. 4, is arranged to rotate in bearingsc and e and between said bearings and the ratchet w'heels c and c on the shaft 0 are placed suitable collars or sleeves o and e to retain the several parts intheir positions on said shaft 0. As will be seen from Figs. 1, 5 and 6, said gov ernor shaft f extends through the bearings e and upon the free end of said shaft, we have arranged a suitable sprocket wheel f whlch consists essentially of an outer ring, preferably provided with suitable sprockets or teeth f and within said ring is arranged friction plates f preferably provided with recesses or chambers f into which extend or project the ends of suitable friction arms f as will be clearly seen from Fig. 6. Of course it will be evident that any suitable friction clutch may be used. On said shaft f are arranged a stationary collar 9 and a sliding collar g, with which are pivotally connected the arms g provided with governor balls g Between said collar g and a collar g secured on said shaftf is a suitable spring g which encircles said shaft as shown, and connected with said sleeve or collarg and sliding in a groove f in the shaft f is a connecting bar h. At certain rates of speedof the train,said governor balls 9 are in the positions, substantially as indicated in Fig. 6, but as soon as the rate of speed of the train increases, the'balls move outwardly, thereby drawing up the collar g and by meansof the connecting bar hand a Washer or collar h connected therewith, two wedgeshaped fingers 71. and h projecting from a collar 7?. pass forward and cause the arms f to moveoutwardly, whereby'said friction plates f and f are brought into binding contact with the inner surface of said ring or sprocket wheel f Said wheel then begins to rotate and by means of a suitable link chain or 'belt z'operates asprocket wheel or pulley secured to the 'end of shaft 2' which is arranged in suitable hangers 1' and 47 in the frame-pieces or supports of the machine. Ou said shaft 1' and a shaft 2' are two reversely arranged conical pulleysl and '1' respectively, which are fixed on said parallelshafts, and encircling the lower pulley l isan endless band- Z As will be seenmore especially from Fig. 1 of the drawings, said band Z which,- as 'li'as been statedfloose'ly encircles on'ly one-of "said pulleys, as the lower pulley Z, moves 'by friction 1 between thever'ysmall spa'ce left between the 1 two cone-pulleys'and is therefore in constant "frictional contact: with the two nearest sur- 1' face edges of the pulleys, whereby,'o\vi;ng to 1 such arrangement of the belt-or band Z9, the action of said hand is more positive and the speedof the one pulleyis instantaneously changed. The positionof "this endlessbai nd ;or belt Z isreguIated by a guide oi-follower Z (see Fig. 3) through which it passes, and said follower is actuated by a screwthreaded rod Z with which it engages and is gsup-ported thereon. By this arrangement of the short friction band l we havederivedthis 1 great advantage, that therewill be no slipg ping of the hand between the cont-act surf faces of thepulleys, as is the case,,wherethe j'belt is arranged to run over,'inste'ad of be- 1 tween the cone-pulleys, and wetherefore obtain a greater and a positive power, and a machine is the result which is capable of do ing the work for which it is intended. Said rod Z is'arranged in suitable hearings on the frame-pieces of the machine, and, as will be seen from Figs. 1, 3, and 10,is operated indirectly from said cone-shaft '6 which in this case is the driven shaft, by means of a very sensitive compound governor M, which in turn is connected by means of a train of gearing N with said screw-threaded rod Z geared in such manner to give the said rod Z a much greater velocity than that of the cone-pulley Z. This causes the follower Z to travel with great speed on the said screw-threaded rod Z while the band travels slowly between the cone-pulleys, and hence said, hand can not burn but still owing to the great speed of the follower'Z is thereby rendered very sensitive and immediately changes the speed of the lower cone-pulley as the speed of the train varies. It is this action of these parts that causes a uniform speed of the shaft t vExtending from the one side of the frame of the machine, as will be seen from said Fig. 1, are suitable arms d and 01 forming brackets or supports for the governor M. The governor shaft m is rotatively arranged in a pedestal bearing 11 in said arm 61 and gearing with a miter wheel m on said shaft m is a miter wheel 6* on the cone-shaft t Said shaft m has arranged on its upper end asuitable governor m which causes, as the speed of the shaft on increases or decreases, a reciprocatory movement of a slide at on said shaft m. On said shaft m are loosely arranged two bevel wheels m and m each of which is provided with a suitable friction device 0 and 0' respectively. In said device 0 connected with said bevel wheels m are the friction clutches 0 and as the speed of the governor is decreased, the spring m causes the downward movement of a rod m attached to said slide m and hence the operative engagement of said bevel wheel m With a large wheel n of the said gear mechanism N, which causes the said rod Z to move in one direction, While, when the governor balls move outwardly, as the speed increases, the friction device 0' becomes disconnected with the bevel wheel m and brings said bevel wheel m into operative engagement with said gear wheel at, which causes said rod 1 to rotate in the opposite direction, as will be clearly understood from an inspection of Fig. 10. In order to prevent the accidental displacement of said clutches 0 they are preferably arranged to slide on projections 0 formed on the inner surfaces of said friction devices 0 and o, as will be seen from Fig. 10. The miter wheel n is connected with a large gear wheel n which ro-t tates on an axial pin n in the arm (Z and which in turn meshes with a pinion n of a greatly reduced diameter, whereby the screw-threaded rod Z receives a greatly increased speed. Thus it will be seen, that the continuous rotary motion of the shaft 1' by means of this system of gearing and the action of the compound governor M will cause the said screwthreaded rod Z to rotate intermittently in opposite directions according to the variations of the speed of the governor and the cone pulley to which it is geared. At the same time, the intermittent reciprocations of the follower l are produced along the rod Z and the governor M having been previously adjusted for a certain speed, any variations more or less will be counteracted by said governor, and the speed of the shaft i is rendered constant, irrespective of the variations of the several other shafts employed in the herein described machine. The construction and operation of said follower Z will be evident from an inspection of Fig. 7, the follower passing backward and forward on said screwthreaded rod 1 according to the change of revolution of the shaft as the speed varies. As will be seen from said figure, said follower is provided with one blind eye Z and ascrewthreaded eye 1 by means of which it moves up and down on said screw-threaded rod. When the follower Z has traversed the entire length of the screw on the rod 1 and the rotary movement of said rod is suddenly reversed, suitable springs 19 or p again force the eye Z upon the screw-threaded portion of the rod, as will be clearly understood.

As will be seen from Figs.1, 2, and 3, we have arranged on the free end of the shaft 1' a sprocket wheel or pulley rover which passes a link chain or belt 1" which produces a retary motion of a wheel r on the armature shaft 8 of asuitable dynamo s. Said dynamo is preferably placed on top of the frame of the speed regulator, but it can be'placed in any other suitable position in the car, as will be evident. From said dynamo extend the circuit wires 8 and s which lead to the lamps within the car or to a storage battery.

The operation of the mechanism is briefly as followsz-When the train starts, the axle 0. causes the revolutions of the shaft b, which in turn causes the operation of the gear shaft 0. All these shafts are adapted to revolve in opposite directions according to the forward or backward movements of the train, but said bevel wheels 0 and 13 cause the shaft f to rotate at all times in the same direction. The governor on this shaft is adjusted for a certain speed, that its sprocketed friction wheel connected with the upper cone-pulley shaft will not become operated until the train exceeds this speed, when the cone-pulleyswill begin to operate and by means of the rod Z and the governor connected therewith, finally bringing the varying speed of the car down to a uniform speed of the dynamo, from which the generated current can be passedinto the lamps in the car or into storage batteries. The essential feature of our invention, therefore, is the arrangement and construction of the novel form of machine herein described, whereby the dynamo is successfully connected with the car-Wheel axle, to maintain an equal power and a uniform speed of the dynamo regardless of the speed at which the train may ICO be traveling, and at all times to cause the dynamo to run inthe-same direction, whether the car is moving forward or backward.

We do not wish to be understood as limiting ourselves to the exact arrangement and construction of the several parts of mechanism comprised herein, for certain changes may be made in the details of construction without departing from the scope of our present invention.

Having thus described our invention, what we claim is- 1. The herein described speed regulating device, comprising therein, a main shaft, a cone-shaped pulley thereon, a driven shaft and a reversely arranged cone-pulley thereon, an

endless band arranged between said pulleys,

and operating by friction with said pulleys, means, whereby said band is caused to travel lengthwise of the pulleys, in either direction, a governor connected with said driven shaft, an automatically operated clutch connected with said governor and said means for causing the said band to travel lengthside of the cone-pulleys, substantially as and for the purposes set forth.
